- Abstract
- Membrane methods of division, in particular return osmosis, allows to lower considerably costs of processing of sewage and to receive water of any demanded quality. Disclosure of the mechanism of selective permeability of baromembranny processes is impossible without research of external factors which influence characteristics of process of division. Data on influence of a hydrogen indicator of initial solution, temperature and working pressure upon selectivity and productivity of serially produced return osmosis (RO) membrane are obtained. Optimum areas of temperatures, working pressure and pH, allowing to reach the maximum results of selectivity and permeability for RO membranes in processes of division of solutions of electrolytes are defined.
